Understanding ATO Vehicle Expense Methods
Cents Per Kilometer Method
The simplest method for claiming vehicle expenses with the following characteristics:
- Claim rate of 0.78 cents per business kilometer
- Maximum claim of 5,000 business kilometers per car per year
- No need for receipts or detailed logbook
- Must be able to explain how you calculated business kilometers
- Can use a different method for different cars
Calculation Example:
3,500 business kilometers × 0.78 cents = $2,730.00 tax deduction
Logbook Method
The most accurate method for claiming vehicle expenses:
- Maintain a logbook for at least 12 consecutive weeks
- Calculate business-use percentage from logbook entries
- Claim this percentage of all car expenses (fuel, servicing, insurance, registration, depreciation)
- Logbook is valid for 5 years unless business usage changes significantly
- Must keep receipts for all expenses claimed
Calculation Example:
Business use: 75%
Total car expenses: $8,000
Tax deduction: 75% × $8,000 = $6,000
Actual Expenses Method
For specific trips or when other methods aren't suitable:
- Calculate actual cost of each business trip
- Keep receipts for fuel purchased for specific trips
- Calculate the business portion based on trip purpose
- Useful for occasional business use of personal vehicle
- Must keep detailed records of expenses and business purpose
Calculation Example:
Fuel cost for business trip: $45
Other expenses allocated to trip: $15
Tax deduction: $60

What's the difference between the cents per kilometer and logbook methods?
The cents per kilometer method is simpler but limits your claim to 5,000km per car per year, calculating at 0.78 cents per kilometer. No detailed records or receipts are required beyond basic trip information.
The logbook method allows you to claim all car expenses based on your business-use percentage. It requires a 12-week logbook and keeping receipts for all expenses but can result in higher deductions for high-use vehicles.
Do I need to record every single trip in my logbook?
Yes, during the 12-week logbook period, you must record every trip (business and personal) to accurately calculate your business-use percentage. After this period, you should continue to track business trips for substantiation purposes, though not necessarily at the same level of detail.
Can I claim both the cents per kilometer method and logbook method?
You must choose one method per vehicle per tax year. However, you can use different methods for different vehicles. For example, you could use the cents per kilometer method for one car and the logbook method for another.
Can I use myBAS logbook for multiple vehicles?
Yes, myBAS allows you to track mileage for multiple vehicles separately. You can create a distinct logbook for each vehicle, track business vs. personal use for each, and generate separate reports for each vehicle.
What if I forget to record a business trip?
If you forget to record a trip at the time, you can add it later in myBAS. Try to include as much accurate information as possible, including the date, starting point, destination, purpose, and approximate distance traveled.
For substantiation purposes, it's best to record trips as soon as possible, but myBAS allows backdated entries when needed.
Can I export my logbook data from myBAS?
Yes, myBAS allows you to export your logbook data in various formats including PDF (for printing/sharing) and CSV/Excel (for further analysis). These exports include all relevant trip details and calculated tax deductions.
